Are there adventages contained by having a curved penis upwards?

I'm not sure...since I'm not average and I've never measured anyone elses. And how come not a soul ever asks how big a girl's thing is?

I want to urinate tremendously often.at most minuscule once every 4 hours.?

Average is between 5-6 inches erect, for a full grown male. And to the first who answered, society don't ask how big a girls thing is because it doesn't business to anyone, girls dont go around resembling OMG MY VAG IS SO BIGGER THAN YOURS. Guys do that, but about their penises.
